Explain how you would find the sum of 46+7

2 answers:

6 0

First, I would break down the 46 into 40 + 6, then add.

40 + 6 + 7
40 + 13 <-- Add the 6 and 7 together
53 <-- Add

So, 53 is your answer.

You can explain how you would find the s like this. I had to add 46+7 and it gave me 53. You need to add the ones first. Which is 6 and 7. Once you've add them up you have to regroup. Last, add up the regrouping part and the 4 tens. (40) it should give you 53. Hope
This helps!!!

Country A produces about four times the amount of diamonds in carats produced in country B. If the total produced in both countr

sveta [45]

Answer:

Country A produces 20,000,000 & Country B produces 5,000,000

Step-by-step explanation:

Let

amount of diamonds produced by country A be x

and

amount of diamonds produced by country B be y

Since, Country A produces 4 times that of Country B, we can write:

x = 4y

Also, both countries produces a total of 25,000,000 carats, so we can write:

x + y = 25,000,000

Now, we need to find x and y. Putting 1st equation into 2nd equation, we get equation in y. Then we solve for y:

x + y = 25,000,000

4y + y = 25,000,000

5y = 25,000,000

y = 25,000,000/5

y = 5,000,000

And now, x = 4y, so x = 4(5,000,000) = 20,000,000

So Country A produces 20,000,000 & Country B produces 5,000,000 diamond carats

The table shows the ratio between the number of books ordered and their cost: Find equivalent ratios when the number of books or

Nana76 [90]

Answer:

The answer is below

Step-by-step explanation:

The table shows the ratio between the number of books ordered and their cost: Number of Books Cost (dollars) 7 21 8 24 9 27 Find equivalent ratios when the number of books ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid.

Answer: Let the number of books be represented as x and the cost (dollars) be represented as y. From the table the ordered pairs in the form (x, y) can be gotten. (7, 21), (8, 24), (9, 27). To get the relationship between the number of books and the cost, we can use the formula of a straight line.

Using point (7, 21) and (8, 24):

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-21=\frac{24-21}{8-7}(x-7)\\ \\y-21=3(x-7)\\\\y=3x-21+21\\\\y=3x$

When the number of books ordered is 1, 2, 3 the following pairs are:

For x = 1. y = 3x = 3(1) = 3

For x = 2 y=3x = 3(2) = 6

For x = 3 y = 3x = 3(3) = 9

The ordered pairs are (1, 3), (2, 6), (3, 9)

The graph is attached

To plot the ordered pairs, the number of books are plotted on the x coordinate and the cost on the y coordinate

Patty is using a cylinder shape container to hold 48 in³ of liquid. The height of the container is 6 inches tall. What is the be

Sati [7]

Answer:

Step-by-step explanation:

Volume of cylinder = πr2h

height =6 inches

r is the radius of the cylindrical container

48 in3 =πr2 * 6

6= πr2

π= 22/7

6*7/22=r2

42/22 =r2

21/11=r2

r2= 21/11

r = SQRT(21/11)

r= 1.38169855942

Doss [256]

Answer:

Step-by-step explanation:

Let X be the number of tickets issued by a meter reader for parking-meterviolations can be modeled by a Poisson process with a rateparameter of five per hour.

X is Poisson with parameter =5per hour

a) the probabilitythat exactly three tickets are given out during a particular hour

= $P(X=3)=0.14037$
